Next iPhone Could Be Completely Waterproof

With Apple expected to disclose more details about the Apple Watch on March 9, consumers are already exciting to see the next-generation iPhone 7.

It seems that Apple has already started working on the iPhone 7 in a major way. The Cupertino-based tech giant recently filed a patent at the United States Patent and Trademark Office describing different methods for waterproofing the iPhone, iPad and MacBook.

In a new patent published this month, and shared on Patently Apple, the company explores the use of a two-part design to make a waterproof iPhone without the need for a case. This waterproof coating is applied to the electromagnetic interference shield as well as to the printed circuit board in the smartphone.

"Many electronic devices are susceptible to water damage because they are not fully sealed and include various openings for charging, connecting peripherals, and inputting and outputting audio. While bulky cases have had a certain amount of success at mitigating water entry through the aforementioned openings, a protective case is of little or no value once water has entered a device housing," according to the patent filed by Apple on March 31, 2014 and published on March 5, 2015.

Last month, Apple CEO Tim Cook said the Apple Watch could be worn in the shower, which means it's water resistant; however, whether that watch is waterproof is still a burning question.

Having a waterproof iPhone could be an awesome feature. Samsung and Sony have both managed to successfully integrate waterproofing on mobile devices.
